The cona supporting-boaring for the sleeve N andstruction and arrangement of this mechanism sprocket L. Inasmuch as thisbracket is seare as follows: cured to the wall of the casing A, which isF is the motor-shaft, which is preferably made of wood, there is dangerof the bea ring arranged parallel to the spindle D and the being thrownout of exact alineinent of the roll C through expansion or shrinking ofthe wood. I therefore provide a construction in which the parts will bepermitted to rotate freely even when the outer bearing is not in exactalinement. To accomplish this, the stubaxle M is terminated a shortdistance within the end of the sleeve N when in its outermost position.

R is a shaft forming an extension of the axle M and having its outer endjournaled in the bearing Q. As the axle M and shaft R both engage withthe sleeve N, they will be held in substantial alinement; but sufficientclearance is provided to allow them to assume a slightly-angularposition without binding. To hold the shaft R in position, the hearing,such as the spring S, secured to the bracket Q, is arranged to engagewith the end of the shaft. This end is preferably tapered to a point toreduce friction on the end of the stub. Axle M is also preferablypointed.

The bearing in the casing A is formed by a comparatively thin plate T ofmetal, and the aperture in the wood is formed large enough to provideclearance, so as to prevent binding.

In operation the winding-roll C is driven whenever the pins O and P arein engagement, and the rewinding-shaft D is driven to rotate in theopposite direction whenever the pinion H is in engagement with thegear-wheel G. These two couplings must be simultaneously operated, sothat the one is disengaged before the engagement of the other, therebypreventing the roll 0 and spindle D from operating against each other.For accomplishing this an operating mechanism is provided, in which U isa lever under the control of the operator. V is a link connecting thislever with an arm W of a rock shaft X, said shaft being verticallyarranged near the rear edge of the casing A and preferably journaled inbearings in the bracket'Y. The rock-arm IV preferably extends in asubstantially horizontal plane and at its outer end has adownwardly-bent portion W, which is connected to the link V. Z is an armprojecting upward from the arm W, which embraces the sleeve N andengages with the groove (Z therein. c is an arm projecting forward fromthe upper end of the rock-shaft X and engaging with the groove 0. Thuswhenever the rockarm W is operated through the medium of the link V thearm Z will be moved to slide the sleeve N into or out of engagement withthe winding-roll C. At the same time the rocking of the shaft X willswing the arm a, so as to slide the pinion H out of or into engagementwith the pinion Gr.

It is usual in ,the construction of pianoplayers to provide a regulatorfor controlling the motor while it is operating the windingroll, whichregulator is thrown out of action during the rewinding. With the presentconstruction the regulator (not shown) is controlled in its operation bythe actuation of a link f, which is connected to a rock-arm 9, securedto the rock-shaft X. Thus the three rock-arms W, a, and f are allsimultaneously actuatedby the operation of the lever U.
